A former Washington, D.C. teacher has vanished without a trace after school officials say they found a pornographic image of a child on a camera he used.

The FBI needs your help finding Eric Justin Toth, who’s accused of producing and possessing child pornography. Toth was added to the agency’s Ten Most Wanted Fugitives list, replacing the spot once taken by Osama bin Laden.

“This is someone who is out there looking. He’s on the prowl for his next victim,” FBI Special Agent-in-Charge, Ronald Hosko, told CNN’s Tom Foreman.

According to the FBI, Toth, 30, may advertise online as a tutor or male nanny. Hosko also told Foreman that the fugitive ex-teacher secretly installed a camera in his third grade bathroom at his private school and charmed families into allowing him to be a tutor and babysitter for young boys.

The FBI warns Toth may be using his computer expertise to evade capture. The agency is offering a reward of up to $100,000 for information leading to Toth’s arrest.
